Always take in mind that colour bombs are much harder to obtain than striped and even wrapped candies.
If there is a line of five candies, in which all but the central candy is of the same colour, and that there is a candy of this colour diagonally between both candies. Generally, you will like to lower the correct candies until they are on the same height and then go to close the gap.
It is possible, but more luck dependent, to form a colour bomb through a vertical match of five by making a horizontal match that closes the gap.
Using the colour bomb
The colour bomb is considered to be the most powerful special candy in the game. It both removes all the candies of this colour and simplifies the board. This will bring you to great advantage in most levels in this game.
In rare cases, if only two colours occupy a column, using a colour bomb on one of the colours will cause the other colour to form another colour bomb and ease your work.
